Fire Rated Glass

Description

ROBAX® glass-ceramic has a thermal endurance far exceeding that of normal tempered glass. Tempered glass is generally limited to applications that do not exceed 500F. However, ROBAX® is designed to operate at temperatures ranging from minus 400F. to plus 1400F.

Glass-ceramic was invented in the 1960s. Its thermal endurance and stability make it ideal for many products: from stove tops and cookware, to missile nose cones and astronomical telescope mirror substrates. Transparent glass-ceramic, introduced in 1970s, is much more difficult and expensive to make than ordinary glass. As a result, it also has a different appearance including color, surface texture, and some small bubbles or inclusions that are natural to its composition and have no effect on its strength or performance.

We've placed a cutting torch below the ROBAX and heated it until red-hot. Then cold water was poured on the glass from above - with NO breakage.
